When did you guys decide to be straight?
I know I never decided to be straight. I just knew that I was because it's what I was attracted to. The only choice I see in it is whether or not you make the conscious choice to actually admit it to yourself, those around you and then be true to yourself and act on it. Or you could hide it and pretend to be straight. That's the only choice I see in it and from what I know based on what friends who are gay have experienced.
Meanwhile, there are others who are attracted to both genders. It's just within them to be that way. People are people.
As for my views: I could not care less if someone is gay or straight. It doesn't effect me. Someone being gay won't make the apocalypse come, it won't end the world. It will have zero influence on your life if two people of the same sex are with each other.
The thing is, most people are uncomfortable by it because they focus too much on the fact that those people are having a different kind of sex than they are. I've found anyway. They stop seeing a gay individual as a person and all they focus on is what they do in the bedroom.
People use a lot of arguments to defend their own bigoted and ignorant view. The bible says it's wrong, cool, the bible also says you shouldn't eat shellfish and slavery is all good. You can't just pull phrases out like that to suit you.
It's not found in nature. Except it is. There are animals who have homosexuality within them.
tl;dr: it doesn't effect you, if it makes you feel uncomfortable, great. Just don't make other people second class citizens because it makes you uncomfortable and you feel it's wrong. You have the right to feel that but leave others be as long as it doesn't effect you.
